The design, synthesis and biological evaluations of eight 4-substituted 5-methyl-furo[2,3-d]pyrimidines are reported. Synthesis involved N4-alkylation of N-aryl-5-methylfuro[2,3-d]pyrimidin-4-amines, obtained from Ullmann coupling of 4-amino-5-methylfuro[2,3-d]pyrimidine and appropriate aryl iodides. Compounds 3, 4 and 9 showed potent microtubule depolymerizing activities, while compounds 68 had slightly
报道了八个4-取代的5-甲基-呋喃[2,3-d]嘧啶的设计,合成和生物学评估。合成涉及N-芳基-5-甲基呋喃[2,3-d]嘧啶-4-胺的N4-烷基化反应,该胺是通过4-氨基-5-甲基呋喃[2,3-d]嘧啶与适当的芳基碘化物的乌尔曼偶合获得。化合物3、4和9表现出有效的微管解聚活性,而化合物68的效力稍低。化合物4、6、7和9抑制微管蛋白组装,其IC50值可与康维他汀A-4(CA-4)相比。化合物3、4和69规避了Pgp和βIII-微管蛋白介导的耐药性,这些机制可能会限制紫杉醇,多西紫杉醇和长春花生物碱的功效。在NCI 60细胞株中,化合物3在47个细胞株中的GI50值小于10 nM。在MDA-MB-435异种移植模型中,化合物3具有统计学上显着的抗肿瘤作用。3的生物学效应将其鉴定为具有抗肿瘤活性的新型有效的微管解聚剂。
